To all whom it may concern:

Be it known that we, Jesse E. Annet/is and JOHN C. TALmrniino, citizens of the United States, residing at laltimore, in the State of Maryland, have invented certain new and useful Improvements in Tools for Applying Caps to Bottles, of which the following is a spe'cication.

This invention has reference to an improved tool for applying sheet metal sealing' caps to the necks of bottles that are provided with a loci-:ing shoulder Yith which the cap engages.

The present invention has particular reiterence to an improved tool that will operate on a primarily smooth `flanged cap to first produce crimps or corrugations therein, then to seat the cap on the neck firmly and nally close the cap intoloclring enga-gement with the neclr all during` ay vertical movement between the tool and bottle neclc.

The invention also consists in the improved construction and arrangement of a solid ring-shaped corrugating member that will simultaneously corrugatethe liange and direct the flange inwardly toward the bottle neck,.and a further feature of the invention is in the combination of a head, a solid ringshaped corrugating member to 'forni the corrugations in a cap flange and a yielding locking member to lock the corrugated flange about the bottle neck.

The accompanying,` drawing,` illustrates the invention in which Figure 1, is a central vertical. section througlra head to which the corrngating and lockingr members are attached. Fie'. 2, is a perspective view of the annular corrugatingmen'iber. Fig. 3, a similar view of the annular locking' member. Fig. el, is a plan view of the vieldin, medium. Fig. 5, i.: a side view ot a smooth hanged cap prior to its application to the bolt-le, and Fig. 6, is a side view oi the cap applied to the bottle neck.

The corrugating member is preferably carriedin a head of suitable form and construction that will permitit to be readily placed therein, and while the particular' construction of the head is immaterial, we have shownin Fig. 1 a head that meets the requirements for all practical purposes. By

Specification of Letters latent.

Application filed December 24, 1908. Serial No. 469,050.

reference therefore to Fig. l it will be seen that the head, 1, has a central stem, 2, that projects upwardly therefrom with a recess, 3, at its upper end and a longitudinal bore or passage, e, intermediate its ends. Between the upperrccess and the lower bore, the

stem is provided with an internal shoulder,

ter normally has position so as to project from the passage mto the circular rec-ss of the head. This plunger head isl preferably provided with a concaved or recessed bottom side, 9, to conform approximately to the shape the cap is to lalie when it is appliedi to a bottle neck. stem projects above the shoulder, 5, and has ahead, 10, which seats-on said shoulder and. thereby limits 'the downward movement of llle stem. A coiled spring, 11, surrounds the The upper end of the stein and compressed between the bottom side oi l he shoulder, 5,'and the upper side of the plunger head in order that the latter head and stem may have a yielding vertical movement to adjust itself to variations in the height of the bottles.

It corrugating or crimping member is provided at the lower end of the central passage and has a position that is concentric. with the plunger head, 8. `While thiscorrugating or crimping member may be embodied in dierci'it mechanical 'for1ns,`we have preferred, in the present instance t'o show the saine in. the vform of a continuous ring, 12, having;- a central uprigl1t,'13. This central ring opening;` is larger at the lower end, 14, than at .its ,upper end, 15, and its curved inner face is provided with. corrugations, 16, that extend from the lower toward the upper end tliereoi",-the corrugations tapering and having their broader portions, l ,adjacent the entrance to the opening. Frein the foregoingdescription it will be seen that the ino crimps or corrugations of this member, in

Above the ringlshaped corrugating member and also in the cent-ral recess, 6, of the `head We provide an annular locking member, 18, which closes the cap-flange about and into locking enga ement with the usual locking bead or shou der on the exterior of the bottle neck. In the present instance the locking member is formed in segmental -sections which when in proper relative relation butt together and have a rin form with a central opening, 19; The wal of this central opening is substantially 'straight in a Vertical direction with the exception of a 'slight bevel, 20, at its lower end where said opening. registers with the opening in the corrugating member.- By referenceito Fig. 1 it will be seen that the segmental locking member also has position in the bottom rccess, 6, of the head and is concentric with and embraces the lower end of the lunger head, 8. These locking-member sections are preferably sustained'alout the plunger head so as to permit them to yield by moving laterally in a radial direction with respect to the plunger head, and while this` lateral movement may be effected in various ways,

*the form of device here shown comprises a yieldingv backing 2l. This yielding backmg, in the present instance, has the form of a rubber ring which encircles the locking member and permits its sections to yield laterally when wedged apart at the central opening', as would occur for example when a bottle neck of a slightly larger diameter than the central opening, 19, is inserted in the latter during the eap-locki1ig operation.

The crimping or corrugating member may be retained in the head in any suitable man v ner but in the present instance we have pro,

vided a base plate, 22, which also has a central opening,'23, and which`is attached to the bottom of the head by means of screws, 24.

rIhe form of cap employed is preferably one that has a depending Wall with a laterally-projecting smooth flange, the particular angle at which the lateral flange projects is immaterial and may be varied but it isA desirable that the depending Wall be pri marily plain and practically free of corrugations or crimps as it is desirable and l advantageous ythat the corrugations be formed simultaneously from all sides while there is a relative vertical movement between the head and the neck with the cap in position thereon. This relative movement may be a downward movement of the head onto the bottle or it may oe-an upward move ment of the bottle and cap into the head. In either event during the entering of the cap and bottle neck vinto the openings, 23, and, 13, the corrugations or crimps are formed, and the further entrance of the cap and bottle neck into thefopening, 19, will Aeffect a locking of the cap about the bottleneck. During` the movement of the cap onto 'the opening', 1), the dome or top surface of perforated plate carried thereby said plate aving a plurality of rigid corrugations. in its perforation and the perforation being. smaller in diameter at one side than the other.

2. In a tool'for operating on the plam flange of metal bottle caps to form corrugations while the cap is on a bottle neck, the

combination with a head, a plate carried by the head and having a perforation with a ,plurality of rigid corrugations in the perforation to corrugate the cap as it is entered with the bottle neck into said perforation, and means beyond the corrugations for locking the same' about the bottleneck.

3. In a tool for corrugating and applying' 95v plain fianged caps to bottles, the combination with a head, of' a central plungerI in the head and a ring below the plunger and having a rigid corrugated interior diameter for.' forming corrugatlons in the cap flange while closing said flange about the bottle neck.-

4. In a tool for corrugating' and applying plain flanged caps to bottles, the combination with ahead having a central recess, and a plate attached to the head below the s aid recess and having a central tapered openm0 largest at its entrance and said tapered opening having a plurality of rigid corrugations exten ing upwardly toward its smaller diameter whereby when a plain flanged cap on the mouth of a bottle is passed through said tapered opening the rigid corrugations therein will form corresponding corrugations in said cap fiange about the bottle neck.

5. In a tool for applying flanged caps to bottles the .combination with a head, of a rigid corrugating device carried by the head, and a locking device.

G. In a tool for applying flanged caps to bottlesthe combination with a head, of a rigid corra-gating device carried by the head, and a yielding locking device.

i. In a tool for applying flanged caps to bottles the combination with Aa head, of a perforated corrugating plate carried by the head and a sectional locking device above the corrngating plate.
